We are excited to share our latest work on making secure messaging more decentralized!

We've developed DMLS – a new approach that brings fork resilience to the MLS protocol, solving a key challenge in distributed systems while maintaining Forward Secrecy.

This work was made possible by eQualitie, who funded it as part of the SplinterCon Breakout program.

Discovery of last week: Wire, the instant messenger headquartered in Switzerland, developed in Berlin and founded by former Skype employees, has experimental support for both Messaging Layer Security and Federation (similar to Matrix), has open source clients and server, and unlike Signal, explicitly allows selfhosting servers.

In case you missed our talk about Messaging Layer Security (MLS) at #37C3, you can re-watch it now.

MLS is the first standardized and fully specified end-to-end encryption protocol. It brings substantial improvements in performance and security compared to existing protocols. We have been involved in the design and development of the MLS protocol since the very beginning.

🍿 The Congress talk:
@raphaelrobert and Konrad presented Messaging Layer Security (MLS). The room was packed and some people couldn't attend in person – luckily the talk is now online and can be watched again.

Thank you @CCC, @c3voc_releases, and all angels for the great event!

We are very excited to be at the 37th Chaos Communication Congress in Hamburg after a long pandemic break. On day 3 (29.12., 3:45pm), @raphaelrobert and Konrad will give a talk on “RFC 9420 – or how to scale end-to-end encryption with Messaging Layer Security (MLS)"
👉 https://fahrplan.events.ccc.de/congress/2023/fahrplan/events/12064.html

@cityroler will be buzzing through the corridors and can be reached via DECT at 4109. If you want to talk about secure messaging or E2EE, let us know!

Our #HKPE (RFC9180) implementation shipped by #OpenSSL has been audited, and passed with flying colors: "Auditors did not identify any directly exploitable vulnerabilities". Nice work, Stephen Farrell!
